Anna copied Rachel's DOA6 Seaside Eden and Xiaoyu copied Leifang's as well. Can't tell with Lili.
From what i can see it looks like they basically took Azu's original T8 bikini she came with and made it for the other girls with different designs which they should have had day one in the game, but its not much imo since the bikini is basic compared to the skirt one we got last summer. The guys tho look promising, at least Lee's since he has a speedo
I say SF6 is winning in the swimwear department tho since at least in that game their swimsuits are all unique even if not everyone's getting one.
The battle pass looks like it may have some promising stuff tho, I like the two tone rogue long hair that's coming thr top looks cute, and I also see the fundoshi too which I like too. It looks like the bulk of the pass stuff tho is gonna be the pac man filler content
